T all whom it may concern:

Be it known that I, NAPOLEON DU BRUL, a citizen of the United States,: and resident of Cincinnati, in the county ,of Hamilton and State of Ohio, have invented certain new and useful Improvements in Tobacco- Cutting Machines, of which the following is a specification.

This invention relates to machines for producing long cut tobacco, particularly that class of such machines which are designed to cut the tobacco into very thin threads, and

has for its object to produce a machine of this kind, which will feed the tobacco uniformly throughout the entire breadth of the mouth and avoid the dragging on the sides of the body of tobacco, which tends to present an uneven front at the shearing edge.

This object is attained by providing the feeding means with confining flanges, which restrict the width of the body of tobacco and prevent its contact with the side wallsof the machine. The flanges are preferably provided on the lower roll of a pair of feed rolls, "immediately in advance of the mouthpiece of the machine, and the space in which the tobacco is confined by the flanges is preferably slightly less than the width of the feeding trough and mouth so that after the tobacco leaves the rollers and passes into the mouth, it will continue to be freeifrom retarding influence at the sides.

The invention will be fully understood upon reference to the accompanying drawing in which, i

Figure 1 is a vertical longitudinal section of those parts of a tobacco cutting machine with which my invention is immediately concerned; Fig. 2 is a front elevation of the 7 upper portion of a tobaccocutting machine having my invention embodied therein; and Fig. 3 is a detail view of the flange roller and its coijperating roller, which condense tobacco immediately, prior to its entering the mouth of the machine. Y

1 represents the mouth of the tobacco cutting machine, which hasa shearing edge 1 with which the cutting knife 6 cooperates in a known manner.

. 2 represents the lower roller and '3 theupper roller of a pair of condensing and feeding rollers, located immediately in advance of the mouth of the machine andin such relation thereto that they cause the tobacco to feed through the mouth to the cuttingcedge.

Under the pressure of the roller 3, the tobacco :hasa tendency 'to spread laterally,

' and it is'found in practice, that thiscauses the sides .of the body of tobacco being fed to 4 V be retarded by the friction of the side walls ofthe machine so that the tobacco does not feed uniformly throughout its width but presents "an uneven front, which results in To overcome this unsatisfactory cutting. dragging eflect, the roller 2 is provided with flanges 2*, one or both of which may be conveniently attached to the roller by screws 2*. These flanges may if desired be so that they will prevent the tobacco dragspaced apart slightly lessthan the distance ibetweenthe' inner side walls of the machine, 170

g'ing against said side walls, and sincethey rot-ate with the roller2, the roller is adapted to lmpart a drive to the sidesof the body of tobacco as well as to its upper'and under .75 surfaces. Theflanges enter *recesses'in the,

mouthpiece 1 and being spaced apartpless f than the width of saidmouthpiece, the t0- bacco, which is delivered by the roller 2, is
